Application filed May 1, 1928, Serial No. 105,643. Renewed March 20,1928.

This invention relates to stoves and other heating devices and has forits principalobiect the provision of means tor the eliiclent utilizationof the heat of the products of combustion after they leave the tire pot,for cooking or general heating purposes.

Another object of the invention 1s to provide flue-means incommunication with the lire pot ot a stove or other source ofcombustion, said means being arranged to torm a compartment whereby theheattrom said means is concentrated within the air space of saidcompartment.

A further object of the invention is the pro vision of a heating deviceforming acketed compartments with lines arranged 111 said ,acketconnm'inicating with the combust on chamber of the heating device fordirecting the how of the products of combustion into heat interchangingrelationship with the walls of said compartments, and being providedwith dampers for selectively diverting the flow of combustion productsfor the pur- Jos-e of heating certain compartments or parts thereoit toa greater or less extent, or to 1mprore the draft by conduct-mg theproducts of combustion directly to the chimney pipe.

Still another object of the invention resides in the construction ofheating apparatus 01' the class described which r ay, if desired, beused as an attachment to stoves already built, or incorporated intostoves, ranges, furnaces or the like at the time of their construction,ease of installation, and accessibility for the purpose of cleanin 7Other objects ot the invention will appear as the following descriptionof a preferred embodiment thereof proceeds.

Figure G is a perspective view showing a modified form of the invention.

Referring now in detail to the several figures, the numeral 1 representsin general, a stove having the fire pot 2, feed door 3, ash pit 4c andash tray the latter being pretertaken along the line taken along theline taken along the line ably provided with a draft damper 6. The stovepreferably is supported upon legs 7 at a distance from the floor. Theparts which have just been described are common to any stove and noclaim is made to them as part of the present invention, except wherenecessarily combined with the structure now to be defined. i

The tire pot is preferably eXtendcd later ally as siown at 8 and 9 inFigure 2, the lateral extensions being formed with flanged openings 10and 11 to receive the flue casing. 12. This casing is in general of aninverted U-shape having vertical limbs 13 and 14 fitting down upon theflanged openings 10 and 11, and joined by a top transverse member 15 andpreferably by an intermediate transvrse member 16. The flue casing maybe made in upper and lower sections as shown, in which event theintermediate transverse members 16 are provided with flanged openings 17and 18 upon which the upper section oi the casing is fitted.

-he vertical limbs and transverse members are double-walled as shown,and provided inside with partitions, as follows, forming fiues. Thevertical limbs 13 and 14 in those parts which lie between the stove andthe. intermediate transverse member are formed as single. conduitsthrough which the products of combustion from the fire pot pass upward.At the level of the bottom of the intermediate transverse member, ahorizon! tal partition 19 is provided in each of the ver 'ical limbsextending part way across said limbs and joining a. vertical partition20 which eXtendsto the top transverse member and part way across thesame, the partitions 20 being discontinuous adjacent the middle of thetop transverse member affording an avenue of communication between thespace wit-hinthe forward part of the top transverse member and the spacewithin the rear part of said member, which latter space is incommunication with the fines 21 formed by the partitions 19 and 20 atthe rear of the vertical limbs. Said fines are in open communicationwith the space within the intermediate transverse member throughopenings 22. "By means of this arrangementof fines, the hot products ofcombustion rise to the top of the verticallimbs through the forwardflues 20' without normally having access to the intermediate transversechamber, and then, passing through the space between the partitions- 20in the toptransverse member, said products of combustion flow downwardlythrough the flues 21 and into the intermediate transverse member, beingdischarged from the same through the chimney pipe 23 after passingaround the distributing baffles 40.

The vertical limbs of the flue casing, together with the top of thestove, intermediate transverse member, and top transverse membertogether, form compartments 24 and 25 surrounded on their top, bottom,and sides by the extensive heat conductive surfaces formed by the top ofthe stove and the flue casing. It is clear that the heat of theproclnets of combustion, which usually pass directly into the chimneypipe and are wasted, are, in the present construction, conce-nt atedwithin the compartments 24 and 25 intensely heating the air thereincontained and assisting in cooking whatever objects may be arranged insaid compartments for that purose. p By the novel arrangement of thepartitions which I have above described, the flow of products ofcombustion is so regulated that the hottest gases contact with the sidesof the compartments and with the top of the uppermost compartment, thetop of the stove being in heat conductive relation to the lowercompartment. In this manner both compartments are substantially equallyheated. may be desirable, however, at certain times to regulate the heatso as to divert the maximum heat to the inter-mediate transverse member.This is done by means of dampers 26 and 27 controlling openings whichlead from the front flues 20 of the intermediate transverse member. Whenthese dampers are opened the combustion products are conducted directlyto the intermediate transverse member and drawn directly out through thesmoke pipe 23. This arrangement is of especial advantage when the uppercompartment 24 is being used as an oven. It may happen that the upperpart of said oven becomes unduly heated. The dampers 26 and 27 may thenbe opened diverting the heat to the lower part of the oven. Opening thedampers has the effect also of providing a direct path for thecombustion products from the fire pot to the smoke pipe, thus improvingthe draft of the heating device. This is particularly advantageous whenstarting a. fire or when attempting to burn up a slow fire.

For convenience in cleaning out soot from the lateral extensions of thefire pot and from the transverse members 15 and 16, I have pro vided theremovable lids 28, 29 and 30. The lid 28 preferably is flanged on allfour edges and fits down over the open end of the upper section of theflue casing. The other lids are preferably flanged only on their frontand back edges as shown at 31 and 32 in Figure 1, and rest uponhorizontal flanges 33 provided at the edges of the respective sectionswith which they are associated. The cover 30,

pot, is provided with In that form of my invention shown in Fig ure 1the stove has been provided, mainly for the sake of design, with hollowpillars and 36 below the vertical limbs of the flue casing, closed fromsaid casing but in line therewith. These pillars are supported upon theupper wall of the ash pit 5, which has been extended laterally on bothsides to meet said pillar This disposition of the ash pit walls makes itpossible to use an ash tray of greater capacity than would otherwise bepossible so that it is not necessary to remove ashes from the stove asfrequently as is ordinarily required. The spaces between the verticalpillars 35 and 36 and the side walls of the fire pot may serveconveniently as warming ovens.

in that rorm of my invention shown in Fig ure 6 there is no intermediatetransverse memher, that the partitions within the flues may be dispensedwith. In this embodiment of my invention the flue casing 37 may be addedas an attachment to a stove already built, and f r this purpose it ispreferable that the easing include the bottom transverse member 38 whichin the form of my inventionvfirst described is part of the fire pot. Thelower face of the bottom transverse member 38 is suitably apertured tofit down upon that part of the stove with which it is to be associated,and the furnace pipe represented by the reference numeral 39 leads fromthe lower face of the top transverse member.

lVhile I have in the above description disclosed what I believe to be apreferred and practical embodiment of my invention, it is to beunderstood that the specific details described are not limitative intheir eii'ect upon the invention but merely illustrative except in farthey are expressly prescribed by the terms of the appended claims.
